Specification: Dimensions: 15mm x 1mm thick (approx. 5/8" X 1/32" thick) Tolerances: ±0.2mm x ±0.2mm (0.01in) Material: NdFeB, Grade N52 (maximum strength) Plating/Coating: Ni-Cu-Ni (Nickel) Magnetization Direction: Axial (Poles on Flat Ends) Max Operating Temp: 176ºF (80ºC) Pull force: approx 2.8 lb (1.27 kg)
Material Features: Neodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available. Neodymium magnets are sometimes known as Neo, Neod or NIB magnets. Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting. Neodymium magnets are made of a brittle material. These magnets are not as strong as steel. They are more like a brittle ceramic. If you let two magnets slam together, they can crack and break. This is true for magnets large and small.
WARNING!!! Strong magnets should Keep away from Ironware and some easily magnetized iron products, such as monitors, bank cards, computers, televisions, mobile phones and other. These magnets are very powerful which should be handled with great care. Without parents supervised do not allow children to playing magnets as they could get injured. Especially pay attention to the small magnets , please place in somewhere children can't reach place.
super fast shipping. Exactly the magnets I needed. I have been searching for this size and finally found a seller.

These magnets are very strong and very thin. When working with them it was hard to pull apart and quite a few of them shattered when they came together again. They worked well for my project. I just had to be careful while working with them to keep them a good distance from each other.
